Why did you need the spares, you going to run 20" Snows?
Why would you use all weather tires for Winter? They are basically just 3 season tires and Winter isn't one of them. Those tires begin to lose optimum grip at just 43 degrees F. As the temp drops the rubber becomes harder. Winter tires will reduce your stopping distance by up to 30% because of a different, more pliable compound. If you are going with all seasons you may as well keep the Continentals on and save the money.
I have been driving for 50 years and only began using 4 dedicated Winter tires about 12 years ago. I agree that all season tires can do a decent job in the snow but people forget that many times they are driving on just cold bare roads. This is where the softer rubber compound proves its worth in stopping and handling. The bottom line is that while an all season may do the job, it cannot match a dedicated Winter tire in overall performance and safety in all Winter conditions. That is one reason why many insurance companies now offer discounts on premiums for using Winter tires and the province of Quebec has made them mandatory.
Just have to drive extra carefully and they plow very quickly here in NY so that helps. Plus I dont have to drive in snow very much like those guys up in Canada lol.
You forget though that biggest advantage of Winter tires is traction on cold bare roads where, unlike all seasons, the rubber remains more pliable. The all seasons begin to stiffen up at 43 degrees F. That is the big misconception between the two tires. Many people still refer to them incorrectly as 'snow' tires and only look at that performance. There is a reason they are now called 'Winter' tires.
